The Z-Wave Alliance, a standards organization for advancing the Z-Wave wireless smart home protocol, announced the new Z-Wave Long Range (Z-Wave LR) specification.
Engineered to provide significantly extended wireless range and support robust networks, Z-Wave LR extends Z-Wave connectivity beyond the interior boundaries of the home to improve wireless transmission range of peripheral Z-Wave devices such as door locks, garage door sensors, gate access solutions, and more, while increasing scalability to over 2000 nodes on a single smart home network.
Developed and managed by the new Z-Wave Alliance Technical & Certifications workgroup, Z-Wave LR ushers in a new era of Z-Wave connectivity and brings expanded options for the smart home, multidwelling units and hospitality use cases.
To ensure complete home or building coverage or expand the network into the yard, most Z-Wave installations today leverage Z-Wave repeaters to strengthen and expand coverage. Z-Wave LR eliminates the need for a repeater within the network by increasing the Z-Wave transmission range. Increased range unlocks new potential for Z-Wave networks, making it easier than ever before to enroll smart home and IoT devices deployed at the end of the yard or beyond for enhanced functionality.
As the average number of installed smart home devices continues to increase, so too does the strain on the network. To support the upward trend in the number of sensor and IoT devices within homes and MDU environments, Z-Wave LR also increases scalability on a single smart home network to over 2000 nodes — a 10x increase from Z-Wave.
As with all certified Z-Wave devices, Z-Wave LR devices can be installed within any Z-Wave network and feature interoperability and backwards compatibility with any previously installed Z-Wave device.
The Z-Wave LR specification will be managed and certified under the Z-Wave Plus V2 certification program, which currently mandates the inclusion of the enhanced S2 security framework and SmartStart. This setup feature enables true plug and play for the consumer smart home.
